I'll keep my Vista for now, until 2 of the following 4 happen:
1) I see enough reviews that say Windows 7 is worth the upgrade and not plagued by security, usability, performance, or compatibility bugs
2) All the development software I use begins to officially support Windows 7
3) I get a DirectX11 graphics card and some game or app that uses it
4) Something I NEED only runs on Windows 7

I just can't jump into a new Windows, after being a victim of the "Express" upgrade to Vista, and watching my Windows 7 RC's boot loader self-destruct after installing updates. (FYI I am making this post from my Windows 7 RC test machine, after having repaired the bootloader with a combination of FDISK and the install disc)

I'm more of a fun when i do nuke and pave of just installing one OS rather then having to have to install one OS, then upgrade to another. Mind you i could always make a back up image of my system when its first set up, but i always forget to

How does this all work if RC7 is already on your machine? Are basically then buying the licence? I clicked the button to buy on The Source"s site but didn"t see any options specifying whether you need 32 or 64 bit.
